You can clone a single cell, but problems occur trying to replicate cells indefinitely. Eventually errors creep in and they lose value or grow cancerous (like in a normal human body). As such new lines are needed to make up for older lines that get damaged by cumulative replication errors and other contamination that creeps in.

Er.. Cloning involves growing a whole new whatever from the source
you're cloning.
When they clone a sheep, they produce a single fertilized egg that's
then implanted into a momma sheep, and it grows into a sheep normally
from there.
You can't clone a single cell.
